Abstract

L'invention concerne un procédé et un dispositif permettant de fournir une application de forme d'onde conforme à l'architecture de communication de logiciel standard (SCA) pour un système radioélectrique défini par logiciel. On utilise un générateur de noyau d'applications pour séparer la mise en oeuvre des ressources de logiciel propres à un tel système radioélectrique, par rapport à la mise en oeuvre de la fonctionnalité de forme d'onde propre à ce système. Ainsi, une couche additionnelle d'abstraction est définie et établie entre les objets de ressources de logiciel qui contrôlent l'accès à une série d'interfaces API de cadre central SCA de couche d'abstraction physique et la fonctionnalité de forme d'onde. Cette couche additionnelle garantit que les API de couche d'abstraction physique interagisse uniquement avec le code source conforme à l'architecture. Ledit code, dérivé des gabarits de ressources de logiciel, garantit en outre la portabilité de l'application de forme d'onde résultante pour le système radioélectrique considéré vers d'autres plates-formes à conformité SCA.
